When working with a parabola, you may need to know the possible inputs (domain, or x-values) and outputs (range, or y-values). This will involve finding the local minimum or maximum (vertex),...
For the graph of a parabola, we would use a quadratic equation y = ax2 + bx + c to represent it. However, there is another way: using a point (the focus) and a horizontal line (the...
There are lots of graphs that are not functions. These relations fail the vertical line test, meaning that there is some ambiguity in the output for a given input. So, what cannot be a...
How To Graph A Quadratic (3 Helpful Tips To Draw A Parabola)
If you want to graph a quadratic, you will need a few points on the curve. You will also need to know which way the graph opens so that you can draw it properly. So, how do you graph a...
The axis of symmetry is a line that splits an object in half to give us “mirror images” on both sides of the line. For a parabola, the axis of symmetry is determined by two coefficients of...
The vertex of a parabola is an extreme value of the function. However, it helps to know when it is a maximum or minimum and when it might touch a coordinate axis. So, what do you need to...
